Title: Ball striking cue with self-locking conical joint
Inventor: GENDRON ALAIN
IPC: A63D15/08
Filed: 1994-06-27
Abstract: A ball  striking cue comprises a butt section, a shaft section, and a self-locking joint for removably interconnecting the butt and shaft sections end to end.  The joint includes the proximate end of the shaft section formed with a conical hole, and the proximate  end  of the butt  section  formed with  a conical  extension.     These  hole  and  extension constitute the unique point of contact between the butt and shaft sections.   They have complementary shapes and the hole has smaller radial dimensions than the extension whereby the extension can be forced in the hole to press fit the extension in the hole and thereby removably interconnect the butt and shaft sections with a spacing between the bottom of the hole and the free end of the extension.  The conical hole and extension widens out and tapers, respectively, at an angle which is function of the nature of their material to enable press fit and retention of the extension  in  the  hole  while  enabling  separation thereof by forcing them axially apart from each other. To facilitate separation of the hole and extension, the proximate end of the butt section has a threaded cylindrical surface on which an internally threaded sleeve is mounted, and the proximate end of the shaft section has an annular abutment surface facing one end of the sleeve whereby the sleeve is rotated to abut against the annular surface and spread the hole and extension apart form each other.

Patent CA-2129463-A1 (CA)
Title: Formaldehyde detecting paper
Inventor: NAKANO NOBUO
IPC: G01N31/22
Filed: 1994-08-04
Abstract: Abstract Detecting paper for detecting the formaldehyde present in the atmosphere is prepared by applying hydroxylamine sulfate and Metanil Yellow that changes its color when exposed to sulfuric acid over a carrier of porous sub-stance.  When the sample gas passes through the porous carrier, the formaldehyde contained in it produces sulfuric acid (H2SO4) by decomposing the hydroxylamine sulfate as a result of the following reaction: 2HCHO + (NH2OH)2H2SO4 ? 2H2C = NOH + H2SO4 + 2H2O.  The sulfuric acid reacts with the Metanil Yellow on the porous carrier, thus leaving a trace of reaction proportional to the concentration of formaldehyde.

Patent CA-2134748-A1 (CA)
Inventor: ELLIS MICHAEL D
IPC: G06T7/00
Filed: 1993-04-30
Abstract: Broadcast segment recognition systems (10) and methods are provided in which a signature representing a monitored broadcast segment is compared with broadcast segment signatures in a data base (412) representing known broadcast segments to determine whether a match exists. Criteria for determining the validity of such a match are provided. In one aspect, signatures re-presenting audio broadcast signals are formed by comparing temporally displaced portions of respective frequency band values within plural frequency bands of the broadcast audio signal. Systems and methods are provided for producing signatures repres-enting intervals of a video signal which compensate for shifts in an edge of a picture (142) represented by the video signal. In ad-dition, signatures characterizing respective intervals of a broadcast signal exhibiting correlation are produced by generating a dif-ference vector (150) for each respective interval and carrying out vector transformations of the different vectors (150) to reduce such correlation. Moreover, signatures characterizing intervals of a video signal are produced with corresponding mask words re-presenting reliability of values comprising the signature. Mask words of first and second signatures thus formed representing dif-ferent portions of the video signal displaced from one another are compared to establish the values of the mask word.

Filed: 1993-05-25
Abstract: The radio communication system (100) comprises a transmitter (104) that transmits information during the predetermined time period assigned to at least one radio receiver (106). A monitoring device monitors a level of traffic associated with each of the predetermined time periods and a measuring device measures a level of traffic associated with the radio receiver (106) over the assigned predetermined time period. An identifying device, coupled to the measuring device, identifies if the level of traffic associated with the radio receiver (106) exceeds a predetermined threshold value during the assigned predetermined time period. A generator, coupled to the measuring device and to the identifying device generates a control signal, and the transmitter transmits the control signal to the radio receiver (106) for reassigning the radio receiver to another of the plurality of predetermined time periods.

Title: A spatially distributed sma actuator film
Inventor: MAYNARD RONALD S
IPC: C23C14/14
Filed: 1994-02-24
Abstract: A flexible VLSI film containing shape memory alloy SMA actuator elements (105) and associated control and driver circuitry is wrapped around any bendable element such as a flexible, hollow tube, catheter tube or the like. The SMA actuator elements (105) are thus spatially distributed around the circumference of the bendable element.  The SMA actuator elements (105) are selectively resistively heated with an electric current through associated decode and driver circuitry, thereby causing a portion of the film to contract. The radical distribution of the SMA actuator elements (105) across the surface of the VLSI  actuator film is such that when properly activated, a device sheathed with the VLSI film is capable of executing highly dexterous maneuvers in three-dimensional space, which was not heretofore possible. The actuator elements are self-guided in that control circuitry, decode circuitry and associated microprocessors, including position mapping means are fabricated in VLSI integrally with the SMA actuator elements. Alternatively, a microprocessor controller may be located at a remote location while communicating with associated driver circuitry on the actuator film.
